FIELD OF INVENTION

The present invention relates generally to the art of exterior walls of buildings, and more specifically to a wall panel, a wall panel system, and a method of installation thereof, for buildings.

BACKGROUND

Cross-Laminated Timber or CLT is a pre-fabricated, engineered wood building material with unique and often superior building, aesthetic, environmental, and cost attributes. CLT wood panels are made by pressing perpendicular layers of lumber together with a layer of formaldehyde-free adhesive. The fusion of orthogonal wood layers is what gives CLT biaxial strength, durability, and stability. CLT can serve as a system-based approach for floors, walls, and roofs to form a high-performance, sustainable, and beautiful mass timber building of virtually any type.

CLT requires less energy to produce than other building materials such as steel and concrete and is made from renewable material. CLT panels may be prefabricated and are also lighter than panels made from other material such as steel, thereby reducing design costs of the building. CLT panels may be connected together to create the floor, wall, or roof.

Most wall panels of a curtain wall system are constructed from glass and aluminum. Not only are these materials expensive, they limit the design of the wall panel, and thus, the wall system.

SUMMARY

In one aspect, a wall panel is provided that includes an infill component, a first extrusion, and a second extrusion. The infill component includes a top side, a bottom side, a first side, and a second side. The panel also includes a notch in the bottom side and a T-flange on the top side. A wall system is provided comprising a plurality of connected wall panels. A method of installing the wall panel system is also provided.

As shown in FIG. 3, a first wall panel 100 a adjacently mates with a second wall panel 100 b. The first wall panel 100 a mates with the second wall panel 100 b via the first extrusion 600 a of the first wall panel 100 a and the first extrusion 600 a of the second wall panel 100 b. A splice plate 620 extends between the first extrusion 600 a of the first wall panel 100 a and the first extrusion 600 a of the second wall panel 100 b (not visible in FIG. 3). A splice plate 620 may also be inserted in the second extrusion 600 b of the first wall panel 100 a and the second extrusion 600 b of the second wall panel 100 a to connect to a second extrusion 600 b of a third wall panel 100 c and a second extrusion 600 b of a fourth wall panel 100 d respectively. The connections to the third wall panel 100 c and the fourth wall panel 100 d are discussed in further detail below and shown in FIGS. 4 and 5. The wall panel system 700 may also include a patch plate 630 to weatherproof the joint between the first wall panel 100 a and the second wall panel 100 b. Preferably, the patch plate 630 is an extruded aluminum patch plate.

FIG. 4 is a front, left perspective view of a third wall panel 100 c installed with the first wall panel 100 a and the second wall panel 100 b of FIG. 3. Referring to FIG. 4, the wall panel system 700 may also include a third wall panel 100 c stacked on the first wall panel 100 a. The notch 400 of the third wall panel 100 c mates with the T-flange 500 of the first wall panel 100 a. Moreover, the second extrusion 600 b of the third wall panel 100 c mates with the second extrusion 600 b of the first wall panel 100 a. The splice plate 620 in the second extrusion 600 b of the first wall panel 100 a, previously shown in FIG. 3, extends between the second extrusion 600 b of the first wall panel 100 a and the second extrusion 600 b of the third wall panel 100 c (not visible in FIG. 4). A splice plate 620 may also be inserted in the first extrusion 600 a of the third wall panel 100 c to connect with the first extrusion 600 a of the fourth wall panel 100 d.

FIG. 5 is a front, left perspective view of a fourth wall panel 100 d installed with the first wall panel 100 a, the second wall panel 100 b, and the third wall panel 100 c of FIG. 4. As shown in FIG. 5, the wall panel system 700 may include a fourth wall panel 100 d. The fourth wall panel 100 d connects with the second wall panel 100 b and the third wall panel 100 c. The T-flange 500 of the second wall panel 100 b mates with the notch 400 of the fourth wall panel 100 d. Moreover, the second extrusion 600 b of the second wall panel 100 b mates with the second extrusion 600 b of the fourth wall panel 100 d, and the first extrusion 600 a of the fourth wall panel 100 d mates with the first extrusion 600 a of the third wall panel 100 c. As shown in FIG. 5, a splice plate 620 extends between the second extrusion 600 b of the second wall panel 100 b and the second extrusion 600 b of the fourth wall panel 100 d. A splice plate 620 also extends between the first extrusion 600 a of the third wall panel 100 c and the first extrusion 600 a of the fourth wall panel 100 d.

Mating the extrusions 600 a, 600 b of the four wall panels 100 a-d forms a joint or intersection in the shape of a “cruciform” or“+” sign. FIG. 6 is a front, left perspective view of the intersection of the wall panel system 700 showing the seals or gaskets 610, continuous splice plates 620, and the patch plate 630. FIG. 6 shows the seals or gaskets 610, splice plates 620, and patch plate 630 of the “cruciform.” The seals or gaskets 610, the splice plates 620, and the patch plate 630 weatherproof the “cruciform” or“+” sign joint of the wall panel system 700.

Although an example four wall panel 100 a-d wall panel system 700 is illustrated, the wall panel system 700 may include additional wall panels 100. The notches 400 and second extrusion 600 b of any additional rows of wall panels 100 mate with the T-flange 500 and second extrusion 600 b of the previous row of wall panels 100. Moreover, the first extrusions 600 a of any additional adjacent wall panels 100 mate with the first extrusions 600 a of the previous adjacent wall panels 100.

FIG. 7 is a first cross-section view of adjacent wall panels 100 of the wall panel system 700. FIG. 7 depicts the vertical mated joint between adjacent wall panels 100. The first extrusions 600 a are connected to the wall panels 100. The first extrusions 600 a may be screwed into the wall panel 100, adhered to the wall panel 100, or otherwise connected. The U-channel may be connected to the attachment flange via staggered fasteners. The U-channel and attachment flange joint may be sealed with silicone to prevent water from entering the joint. The first extrusions 600 a may include open cell foam to act as a thermal break or thermal barrier. The splice plate 620 may slide between the seals or gaskets 610 to allow for different distances between adjacent wall panels 100 and to allow expansion and contraction of the wall panels 100. The ends of the splice plate 620 may be thicker to prevent the splice plate 620 from slipping through the seals or gaskets 610 and becoming disengaged from the first extrusions 600 a. FIG. 7 shows an undisplaced position of adjacent wall panels 100. The distance between adjacent wall panels 100 at this position may be approximately 1.5″.

As further illustrated in FIGS. 8 and 9, the first extrusions 600 a and splice plate 620 connection permits a varying degree of displacement between adjacent wall panels 100.

However, FIG. 8 depicts the adjacent wall panels 100 in a closer or closed position. The ends of the splice plate 620 are touching the backs of the U-shape channel of the extrusions 600 a. At this position, the adjacent wall panels 100 are the closest together representing a minimum joint dimension. The distance between adjacent wall panels 100 at this position may be approximately 0.29″.

FIG. 9 is a third cross-section view of adjacent wall panels 100 of the wall panel system 700. FIG. 9 shows the wall panels 100 and joint of FIG. 7 and FIG. 8. However, FIG. 9 depicts the adjacent wall panels 100 in a farther or open position. The ends of the splice plate 620 are against the seals or gaskets 610. At this position, the adjacent wall panels 100 are the farthest apart representing a maximum joint dimension. The distance between adjacent wall panels 100 at this position may be approximately 2.332″.

FIG. 10 is a first cross-section view of stacked wall panels 100 of the wall panel system. FIG. 10 depicts a cross-section view of the mated horizontal joint between stacked wall panels 100. The second extrusions 600 b may be screwed into the wall panel 100, adhered to the wall panel 100, or otherwise connected. The U-channel may be connected to the attachment flange via staggered fasteners. The U-channel and attachment flange joint may be sealed with silicone to prevent water from entering the joint. The second extrusions 600 b may include open cell foam to act as a thermal break or thermal barrier. The splice plate 620 may slide between the seals or gaskets 610 to allow for different distances between stacked wall panels 100 and to allow expansion and contraction of the wall panels 100. The ends of the splice plate 620 may be thicker to prevent the splice plate 620 from slipping through the seals or gaskets 610 and becoming disengaged from the second extrusions 600 b. FIG. 10 shows an undisplaced position of stacked wall panels 100. The distance between stacked wall panels 100 at this position may be approximately 0.65″.

As further illustrated in FIGS. 11 and 12, the second extrusions 600 b and splice plate 620 connection and the T-flange 500 and notch 400 connection permits a varying degree of displacement between stacked wall panels 100. FIG. 11 depicts stacked wall panels 100 with minimal displacement. While, FIG. 12 depicts stacked wall panels 100 at a greater displacement.

FIG. 11 is a second cross-section view of stacked wall panels 100 of the wall panel system 700. FIG. 11 shows the wall panels 100 and horizontal joint of FIG. 10. However, FIG. 11 depicts the stacked wall panels 100 in a closer or closed position. The ends of the splice plate 620 are slid further into the U-channels of the second extrusions 600 b. The T-flange 500 is also further inserted in the notch 400 of the stacked wall panel 100. At this position, the stacked wall panels 100 are the closest together representing a minimum joint dimension. The distance between stacked wall panels 100 at this position may be approximately 0.312″.

FIG. 12 is a third cross-section view of stacked wall panels 100 of the wall panel system 700. FIG. 12 shows the same wall panels 100 and horizontal joint of FIG. 10 and FIG. 11. However, FIG. 12 depicts the stacked wall panels 100 in a farther or open position. The ends of the splice plate 620 are close to the seals or gaskets 610. Additionally, the T-flange 500 is closer to the opening of the notch 400 in the open position. At this position, the stacked wall panels 100 are the farthest apart representing a maximum joint dimension. The distance between stacked wall panels 100 at this position may be approximately 0.988″.
